What to Do When Your Air Conditioner Unit Freezes Up Be careful if your refrigerant line is frozen! The freeze can easily back up to your condenser unit outside, causing problems. If there is too much condensation build-up on the coils, then the water droplets will not drain or evaporate properly.Ī broken blower fan can also cause a refrigerant line to freeze without the hot air moving over the proper parts. When your blower fan is on the fritz, it significantly changes the airflow inside your air handler.
Oftentimes your blower fan can become damaged or break during operation. How efficiently your air conditioner creates cool air and makes it available to you is a hundred percent dependent on your unit having the correct balance of air pressure and airflow. The blower fan helps “suck” the hot air out of your home, which the denser cold air moves to replace. Your air conditioner blower fan helps get cold air where it needs to go and get the warm air outside.Īs the air cools inside of your air conditioner, it becomes denser and does not travel as well.
MY IPHONE FROZE UP WHAT DO I DO PROFESSIONAL
Regular checkups from an HVAC professional can keep your AC’s coils clean. But when the drip pan overflows, the evaporator coils will become waterlogged and freeze.ĭirty coils can cause freezing because the layer of dirt on top of the coils can prevent them from absorbing the water quickly. Usually, this is not a problem because the condensation droplets fall off the coils into the drip pan. The coils pull the water out of the air, which makes condensation builds upon them. One of the reasons your evaporator coils can freeze is that apart from cooling the air inside your home, air conditioners also dehumidify it. Again, ice obstructs the proper airflow of your system - so what starts as a little bit of frost can spiral out of control into a solid block of ice. Dirty CoilsĪ dirty air conditioner coil is the third most common cause of AC freezes. You will want to also look for blocked ducts, closed or blocked grates, and closed dampers. Inspect all the air vents in your home, holding your hand in front of them to feel for air leaking from the sides of the grate.
Even if they are clean, inadequate airflow could still be the issue. If your AC cannot get enough air, then there will not be enough heat (from the warm air in your home) to prevent the condensation on the coil from turning into ice.Ĭheck and replace your air filters first. It is recommended that you have an HVAC professional inspect your home as soon as possible to repair it. If your air conditioner does not cool anymore, it is likely that it has water damage. The ice may melt, and then you will notice that the airflow behavior has stopped - but you are not getting any cooling from the system. When the refrigerant level gets too low, your air conditioner cannot freeze the line. You might not notice a change in your system’s performance with minor frost, but too much ice will affect the airflow.Įventually, the ice will act as an insulator and prevent the air conditioning system from functioning correctly, and the R22 refrigerant will evaporate faster. As the warm air, moist from your house moves over the AC’s evaporator, the moisture will freeze and condense on the coils, and ice will begin to form! If something happens and there is a sudden change in the pressure in your AC unit, the change in pressure can cause the chlorodifluoromethane to act differently.
